Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for joining various members, and can be used, for example, as an opening/closing door of a cabinet.

The structure of the conventional example and its problems Hereinafter, a conventional device for joining members will be described, taking as an example a device for joining members that are used up for opening/closing doors of a cabinet.

Tying of parts used for opening/closing doors of cabbies, watos, etc. This will be explained below with reference to the drawings.

In the figure, reference numeral 1 denotes a door, and a connecting member made of synthetic resin having elasticity is integrally formed with a protrusion 2 having a substantially T-shaped cross section on the back surface, and one end has the protrusion 2. A clamping part 31 that clamps the side and bottom surfaces of the flat plate part 21L of the strip 2
, 3b, and a clamping portion 38. , 3b, and a shaft holding portion 3C is provided at the other end.
(1 and 3e are formed.The shaft holding part 3d,

It holds and is rotatable with respect to the shaft 4.

The connecting device of the members configured as above is only fitted using the elasticity of synthetic resin, and when a large load is applied in the direction of arrow A when opening and closing the SL, as shown in Fig. 4, it will collapse. There was a drawback that the connecting member 3 was deformed and the claws 32L', 3b'75 at the tip of the clamping member 3J3b(7) were displaced from the protrusions. Furthermore, as shown in FIG. 6, a device was invented in which the connecting portion moves along the protrusion when a load is applied in the direction of arrow B. In the figure, reference numeral 5 denotes a door, and a protrusion 6 is integrally formed on the back side of the door, and a recess 6a is provided in a part of the protrusion.On the other hand, a protrusion γa is formed on the connecting member 7. The protrusion 7N is inserted into the hole 6.
aK@memewase.

Even if a load is applied to the member coupling device configured as described above in the direction of arrow B shown in FIG. In response to a load in the incoming direction, the connecting portion would shift toward the protrusion 6.

Purpose of the Invention The present invention has been combined with the present invention in view of the above-mentioned conventional problems, and provides a member in which the connecting member does not easily come off or move even when subjected to loads from multiple directions. The purpose of the present invention is to provide a coupling device.

Structure of the Invention In order to achieve the above-mentioned object, the member joining device of the present invention includes a first member which forms a protrusion having a substantially T-shaped cross section and a hole is provided in a part of the flat plate portion of the protrusion. , a clamping part that clamps the flat plate part of the protrusion from the side and below, and a third member that fits into the hole and holds the second member provided with the protrusion and the clamping part of the second member. The third member can prevent the second member from coming off from the first member.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3A and 3B.

In Figs. 1 to 3 A and B, the door is formed by extrusion molding of 11-piece aluminum or resin, and is provided with a protrusion 12 having a substantially T-shaped cross section on the back side. Flat plate portion 12 of protrusion 12? - A four part 13 is formed on the top.

Further, the connecting member is made of synthetic resin having elasticity of 14 degrees, and clamping parts 14&, 14b are provided at one end, and a groove 16, 16 is formed between the clamping parts 14a, 14b. A protrusion 18 is formed in the portion between the slits 15 and 16, which fits into the recess 13. Furthermore, the clamping portions 14a and 14b of the connecting member 14
The holding member 19 is made of metal and is provided with a window 21 having a similar shape to the protrusion 12 inside the flat plate 20. A side plate 22 is provided vertically from both end faces of the side plate 20, and a claw portion 22a is provided at the tip end of the side plate 22. Further, a bent portion 23 is provided at the lower part of the flat plate 2o.

The assembly procedure of this embodiment configured as above will be explained below.

First, the connecting member 14 is attached to the holding part 14 on the protrusion 12 of the door 11.
It is attached using the elastic deformation of 2L and 14b. that time,
The protrusion 18 provided on the connecting member 14 and the recess 13 provided on the protrusion 12 are engaged. Next, the holding member 19 is held between the holding parts 14a of the connecting members 1 and 4.

14b from the outside. At this time, the claw part 22ai at the tip of the side plate 22 of the holding member 19 climbs over the clamping parts 142L and 14b, and securely fixes the clamping part. Further, the bent portion 23 is formed on the side wall 12b of the protrusion 12.
The main holding member 19 and the connecting member 14 are in contact with the protrusion 12
Prevent it from coming off upwards with +hL.

As can be seen from the above description, this embodiment prevents the engagement between the connecting member 14 and the protrusion 12 of the door 11 by sandwiching the holding parts 14a and 14b of the connecting member 14 with the holding member 19. The connection member 14 can be made more solid, and the connection member 14 can be removed easily.
Movement on the protrusion 12 can be prevented from IL.

Effects of the Invention As has become clear from the above explanation, the member coupling device of the present invention includes a coupling member having a clamping portion that clamps the protrusion.
Since it is configured to be held between the holding members from the outside, the connecting member can be easily moved outside. This is effective because it prevents the material from moving along the protrusions.
